k-rough Heyting algebras were introduced by Eric San Juan as an algebraic formalism for reasoning on finite increasing sequences over Boolean algebras in general and on generalizations of rough set concepts in particular. ...

Fuzzy possibilistic logic is an important formalism for approximate reasoning. It extends the well-known basic propositional logic BL, introduced by Hájek, by offering the ability to reason about possibility and necessity ...

In this monograph highlights the huge concern with evidence and the difficulties encountered by the students and by the challenges that the guide with teaching and learning of algebra, currently always present in the ...

Often, we assume that an action is permitted simply because it is not explicitly forbidden; or, similarly, that an action is forbidden simply because it is not explicitly permitted. This kind of assumptions appear, e.g., ...

Iniciativas recientes apuestan por una enseñanza del álgebra desde Educación Infantil fomentando el modo algebraico de pensar y de actuar con objetos, relaciones, estructuras y situaciones matemáticas. Este movimiento ...

This work is a qualitative case study which aims to research the relevance of the contents of the disciplines that address rings and groups in the pre-service teacher course in Mathematics of the Federal University of Santa ...

Difficulties in learning algebra found on high school, especially among students of the first year have motivated this research, in order to discover and understand the origins of the problem and consider proposals for ...
